HAMIVIOCK-SUPPORTING STRUCTURE.

SPECFIGATION forming part of Letters Patent No. 443,544, dated December 30, 1890.

Application led March 10, 1890.

To @ZZ whom it may concern.-

Be itknown that I, THEoDonn A. ROHRMAN,

i a citizen of the United States, and a resident of Philadelphia, Pennsylvania, have invented certain Improvements in Ham mock-Supporting Structures, of which the following is a specification. p

The object of my invention isto construct a portable hammock support which when extended will provide a strong and rigidlybraced frame-work, but which can be readily folded up into compact form for transportation or storage. This object I attain in the manner hereinafter set forth, reference being had to the accompanying drawings, in which- Figure l is a perspective View of myimproved hammock-support, showing the same extended in position for use. Fig. 2 is a perspective view of the same in its folded condition. Fig. 3 1s an enlarged sectional view of a looking device forming part of the structure. Fig. 4c is a perspective view of part of said device, and Fig. 5 is a sectional view of a hinge-joint of one of the braces.

The supporting structure comprises four posts A, constituting opposite pairs of posts, one at the head and the other at the foot of the hammock, and to each of these pairs of posts is pivoted a yoke B, having at the outer end a hook a, one of these hooks receiving the ring at one end of the hammock cord or rope, while the other receives the ring at the opposite end of said rope. When the yokes are extended and the hammock is swung between the hooks d, said hooks are in a higher plane than the pivots h of the yoke; hence the strain upon the hammock tends to pull the yokes inward, or toward each other, this movement, however, being resisted by contact of arms d upon the yokes with stops f upon the posts A of the frame.

The bracing structure for each pair of posts consists of an upper bracing-frame D and a lower bracing-frame F, each of these frames being hung to a transverse brace-rod g, connecting the posts of the pair so that each of the bracing-frames D and F is free to swing on its rod, the rod carrying the upper frame D being above the rod which carries the lower frame F. The opposite pairs of posts are also Serial No. 343,306. (No model.)

connected bylongitudinal side braces J, each composed of two bars, which are hung to the rods g at the ends, and are pivoted together in the center by means of a transverse rod yzo, the hinge-joint at the center of each brace J being such that it can yield upwardly, but cannot be depressed below a horizontal line. (See Fig. 5.)

The opposite bracing-framesD unite at their inner ends in the plates h,which are connected by means of a pivot-pin t', as shown in Fig. 3, and each of these plates h has an outwardlyprojecting rod m, which serves as a guide for a block p, pivot-ed to the inner end of the corresponding bracing-frame F.

Then the supporting structure is set up in position for use, the bracing-frames D D and J J occupy a substantially horizontal position,

While the frames F are inclined upward fronr Y their pivot-rods to the sliding blocks p, the latter being at the inner ends of the guide-rods m, and being locked in this position by means of a turn-buckle s,whicli engages with headed pins t onA the sliding blocks p, as shown in Fig. 3. By this means a firm and rigid bracing of the opposite pairsof posts Ais eected, yet upon releasing the pins t from the control of the turn-buckle either set of braces may be readily turned upward, so as to permit the opposite pairs of posts'to be brought closely together, as shown in Fig. 2, the blocks p of the lower braces slidingoutward on the guiderods ml as the braces are thus turned upward.

In order to provide an additional support for the structure, I in some cases provide a pendent leg G, having a suitable foot w', carrying the rod w, this leg being forked at the upper end and hung to the pivot-rod t', which connects the braces D D.` As the inner ends of the braces D rise, therefore, there will be a simultaneous upward movement of the meeting ends of the side braces J, movement being imparted thereto through the medium of the leg G and rod w. The side braces J may, however,be disconnected from the other parts of the bracing structure, if desired.

My invention provides a hammock-supporting structure which when folded occupies but a small space, and can be readily stored away within the house, or can be conveniently trans- ICC and a bracing structure comprising upper and i lower bracing-frames pivoted to the posts, the upper frames being pivoted together where they meet, and the lower bracing-frames having at their inner ends sliding blocks guided 1 on the upper frames,substantially as speci tied.

2. The combination ot the opposite pairs ot posts and their hammock-supporting yokes with the bracing structure, comprising thc upper bracing-franies pivoted to the posts and piroted together at their meeting ends, the lower bracing-frames pivoted to the posts and having at their inner ends sliding blocks specified.

3. The combination of the opposite pairs of pairs et posts and haring arms for contact with stops on the posts tolimit the movemen t et the yokes, substantially as specified.

l. The combination ofthe opposite pairs of posts and their hammock-supporting yokes with upper, lower, and side braces pivoted to said opposite pairs ot posts, the upper and side braces being pivoted together at: their meeting ends and the lower braces having sliding` blocks guided on the upper braces, substantially as specified.

5. The combination ofthe opposite pairs of j pests, the pivoted side braces connecting the same, the transverse rod connecting the meeting ends of the opposite side braces, intermediate pivoted braces, and a pivoted pendent; leg carried thereby and 'arrying said trailsierse rod, substantially as specitied.

In testimony whereof I have signed my l name to this slgieciiicatiou in the presence of guided on the upper frames, and a pivoted j locking-lever for said blocks, substantially as I two subscriltiing witnesses.
